Mixture of biomass to energy reuse

Abstract

Focusing on the reuse of the energy and aiming at the thermal and kinetic characterization of sewage sludge and its mixture, with pruning residues (50 mass%), the thermogravimetry was used. The kinetic study was elaborated from the local isoconversional integral method in heating rates 10.0, 20.0 and 30.0°C min-1 at a temperature ranging from 219 to 386°C at nitrogen atmosphere, in a flow of 100 mL min-1. The average activation energy of sewage sludge sample revealed the value of 219 kJ mol-1 and that of the mixture 161 kJ mol-1 , supporting the incorporation of pruning residues in the sewage sludge. During the degradation process, a remarkable increase in activation energy was noticed that ranged from 20 to 70% conversion in the sewage sludge sample, and regarding the mixture, an almost linear behavior was observed during the decomposition reaction. There was no evidence of kinetic compensation effect in the performed studies. The evaluation of the thermal characteristics, as well as the kinetic study of the degradation of sewage sludge and its mixture with pruning residues, can lead to important insights and contribute to a better use of energy regarding the environmental issues.

Navigating Pyrolysis Implementation—A Tutorial Review on Consideration Factors and Thermochemical Operating Methods for Biomass Conversion

“…It is very possible to perform any kind of thermal conversion process in combination with different feedstocks while considering the thermal and kinetic characterization for the target end product; this can be performed by knowing the physical and chemical properties of the material, thus allowing for the right selection, based on the characteristic properties of the individual types. Furthermore, Braz and Ribeiro [108] investigated a mixture of sewage sludge with pruning residues in a proportion of (50 mass%); they compared the results with the sewage sludge without a mixture to determine the thermal and kinetic characterization of the samples. The result shows that the average activation energy value of the sewage sludge Furthermore, Braz and Ribeiro [108] investigated a mixture of sewage sludge with pruning residues in a proportion of (50 mass%); they compared the results with the sewage sludge without a mixture to determine the thermal and kinetic characterization of the samples.…”

Pyrolysis Kinetic Analysis of Biomasses: Sugarcane Residue, Corn Cob, Napier Grass and their Mixture

“…There was a study about advantages and disadvantages of various biomasses comparing with coal [47]. The study of biomass-biomass mixture was found only in the study of Nozela et al [48]. Their study indicated that the mixture of sewage sludge and pruning residues by 1:1 could reduce the activation energy and gave higher heating value than the pure ones.…”

The Potentiality of the Energy Generation From Slaughterhouse Sludge and Wood Sawdust

“…Sendo que a aplicabilidade está condicionada à composição química, propriedade físicas e potencial poluidor do material residual. Pode-se dizer que trata-se de uma forma de reciclagem já que envolve submeter os resíduos a um processo de transformação química que levará à geração de algum produto de valor mercadológico como no caso da produção de energia (Borowski et al, 2002;Nozela et al, 2018).…”
